Abstract

Penelitian sel surya mengalami peningkatan yang signifikan, khususnya penelitian mengenai Dye Sensitized Solar Cell (DSSC) dikarenakan fabrikasinya yang mudah dan murah dibandingkan dengan sel surya konvensional. Penelitian ini menggunakan material semikonduktor nanokristalin TiO2 (T) yang dikompositkan dengan graphene (G) secara laminat yang bervariasi sebagai fotoanoda DSSC. Penelitian ini bertujuan untuk menganalisis pengaruh waktu ultrasonikasi pada sintesis graphene dan susunan laminat graphene TiO2 terhadap unjuk kerja DSSC menggunakan dye ekstrak ketan hitam (Oryza sativa glutinosa) sebagai photosensitizer. Graphene disintesis menggunakan metode modifikasi Hummer dengan variasi waktu ultrasonikasi yang berbeda. Unjuk kerja DSSC diukur dengan solar simulator dengan input daya sebesar 200 W/m2. Dari hasil penelitian didapatkan variasi susunan laminat T/G/T menggunakan graphene dengan waktu ultrasonikasi 90 menit pada saat sintesisnya memberikan efisiensi terbaik sebesar 0.014%. Diketahui juga bahwa susunan T/G/T lebih baik daripada T/G dan terdapat trend penurunan efisiensi DSSC seiring dengan lama waktu ultrasonikasi sintesis graphene. =============================================================================================== The research of solar cell these days has increased significantly, particularly in the research of Dye Sensitized Solar Cell. It is because of its convenient and low cost fabrication. In this research, DSSC photoanodes was made from semiconductor materials graphene-TiO2 which has been composited in laminate with different arrangements. The research aims to analyze the effect of ultrasonication time and laminate composite arrangement on the performance of DSSC using black rice (Oryza sativa glutinosa) as photosensitizer. Graphene was synthesized using modified Hummer’s method with different ultrasonication time. The performance was measured by solar simulator with 200 W/m2 power input. The sample with T/G/T composite laminate arrangement and 90 minutes ultrasonication showed the highest efficiency (0.014%). It is found that T/G/T arrangement showed a better performance than T/G and there is a decreasing trend of the efficiency as the ultrasonication time goes by in graphene synthesis.
